Consider the following intermediate chemical equations. 2
C(s)+102(g) → CO(g)
CO(g) + 2O2(g) –> C0,00)
How will oxygen appear in the final chemical equation?
O O2(g)
as a product
O2(g)
as a reactant
O(g) as a product
20 (9) as a reactant

O O2(g) as a product

Explanation:

it is because oxygen is a gas and it must be given off in form of combustion

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
